Referring to fig. 2 to 4, the rack unit 2 includes a base 21, a main frame 22 extending from the base 21 in a bar shape, and an inclined tube frame 23 connected to the base 21 and the main frame 22. The main frame 22 has two slide rails 24 spaced apart in the left-right direction W. Two protruding rails 241 protruding in the front-rear direction at intervals are provided in the slide rail 24, and two surfaces of the protruding rails 241 facing each other in the front-rear direction are sliding surfaces 242. Referring to fig. 5, in other variations, each sliding rail 24 may be replaced by an aluminum extrusion to directly integrally form each protruding rail 241, and the sliding surfaces 242 of the protruding rails 241 are arranged at intervals in the front-rear direction of the main frame 22.

Referring to fig. 2 and 3, two fixed armrests 3 are fixed on the left and right sides of the frame unit 2, so that a user can hold the fixed armrests 3 while stabilizing the center of gravity in the upper and lower embodiments, but in other variations, the fixed armrests 3 can be omitted.

Referring to fig. 3, 4, 7 and 8, the two handle units 4 are slidably disposed on the sliding rail 24, a roller 43 capable of rolling along the sliding rail is disposed between the handle 42 and the sliding rail 24, the roller 43 has an annular rolling surface, the handle 42 and the rotating shaft of the roller 43 form a fixed connection relationship, and the handle 42 and the rotating shaft of the roller 43 are fixedly connected. Each handle unit 4 further includes a first mounting plate 41 disposed between the roller 43 and the handle 42, the roller 43 and the handle 42 are disposed on the left and right sides of the first mounting plate 41, the roller 43 is disposed on the inner side of the first mounting plate 41, and the handle 42 is disposed on the outer side of the first mounting plate, and the roller 43 on the inner side of each first mounting plate 41 may have a plurality. The rollers 43 of the present embodiment are arranged in a single row along the up-down direction, the rollers 43 are disposed at intervals in the up-down direction H, and the rollers 43 roll on the slide rails 24 to drive the handle unit 4 to slide in the up-down direction H. In other embodiments, only one roller 43 may be provided, and the handle 42 may be directly fixedly connected to the rotating shaft of the roller 43 without being fixed by a mounting plate.

The number of the rollers is four, two adjacent rollers are arranged in a group in the up-down direction of the sliding rail 24, and because the main frame 22 is obliquely arranged from bottom to top to rear, when the handle 42 moves upwards, the rollers 43 are pressed towards the rear side of the sliding rail 24, when the handle 42 moves downwards, the rollers 43 are pressed towards the front side of the sliding rail 24, and when a user moves, the upward and downward speeds are different, so that the pressures on the front side and the rear side of the sliding rail 24, which are received by the rollers 43, are different, the abrasion of the rollers 43 is also different, the rolling surface of the rollers is uneven, and the user can shake when operating the utility model. Therefore, one roller 43 of each set of rollers 43 is contacted with the front sliding surface 242 of the sliding rail 24, and the other roller 43 is contacted with the rear sliding surface 242 of the sliding rail 24, namely, the roller 43 and the sliding rail 24 form single-side contact sliding, specifically: the four rollers are respectively a first roller, a second roller, a third roller and a fourth roller from top to bottom, the first roller and the second roller are in a group, the third roller and the fourth roller are in a group, the first roller and the third roller can be in contact with the front sliding surface 242 or the rear sliding surface 242 of the sliding rail, the second roller and the fourth roller are correspondingly in contact with the rear sliding surface 242 or the front sliding surface 242 of the sliding rail, the first roller and the fourth roller can also be in contact with the front sliding surface 242 or the rear sliding surface 242 of the sliding rail, and the second roller and the third roller are correspondingly in contact with the rear sliding surface 242 or the front sliding surface 242 of the sliding rail. When the handle 42 moves upward, the roller 43 in contact with the rear sliding surface 242 provides a force for upward movement of the handle 42, and when the handle 42 moves downward, the roller 43 in contact with the front sliding surface 242 provides a force for downward movement of the handle, and the upward and downward movement speeds are different, so that the force of the roller 43 by the sliding rail is different, and therefore, the roller 43 is only pressed by one side of the sliding rail 24 due to contact with one side of the sliding rail, the wear is even, and shake caused by uneven wear of the roller is eliminated. When there is only one roller 43, the rolling surface contacts with both the front and rear sliding surfaces, and attention should be paid to the precision of the cooperation between the roller 43 and the convex rail 241, and the processing precision requirements for the roller 43 and the convex rail 241 are high. In other embodiments, the plurality of rollers 43 may be two or six or eight rollers, and the like may be grouped in pairs, with two rollers being less costly, but the first mounting plate may be shorter in length due to the smaller number of rollers, and accordingly, less stable. The stability of the first mounting plate 41 and the handle 42 is improved by more than four rollers, but the cost of the rollers is correspondingly increased by increasing the number of the rollers 43. The number of the rollers can be two or two, and the two rollers are respectively contacted with one sliding surface 242 of the front sliding surface 242 and the rear sliding surface 242, so that the rollers are uniformly worn.

However, in other variations, the rollers 43 may be double-row rollers, or the rollers 43 may be self-lubricated guide sleeves, and the sliding action may be achieved by matching the guide rail 24 with a guide post type design.

Referring to fig. 5 and 8, the rolling surface of the roller 43 is a cylindrical surface, the cross section of the rolling surface is an i-shape with a low middle and high two sides, the middle of the rolling surface is a straight line, the shape of the convex rail 241 is a rectangle matched with the roller 43, therefore, the middle of the roller is a rolling surface matched with the sliding surface 242 of the convex rail 241, two sides of the rolling surface are constraint surfaces, the constraint surfaces are contacted with the left and right side surfaces of the convex rail 241 to limit the roller on the left and right sides of the convex rail 241, the roller 43 rolls along the sliding rail 24 in the up-down direction, the constraint surfaces can prevent the roller 43 and the handle 42 connected with the roller 43 from moving left and right, and accordingly, the sliding surface 242 is a plane. The I-shaped roller and the rectangular convex rail are common, so that the processing maturity is high, the processing is easy, and the cost is low. In other embodiments, referring to fig. 6, the rolling surface of the roller 43 is a progressive conical surface, the cross section of the roller is a middle low side high side ") (" type ", and correspondingly, the cross section of the convex rail is a convex arc matched with the roller. At this time, the cross section of the sliding rail is circular or arc-shaped or the combination of arc and straight line has arc shape, but it should be noted that the shapes of the sliding rail 24 and the roller 43 should limit the movement of the roller 43 in the left-right direction of the sliding rail 24, so as to avoid the left-right movement of the handle 42. The rolling of the roller 43 on the track is smoother, but the manufacturing cost is slightly increased, because the transition between the rolling surface and the restraining surface is more rounded.

Referring to fig. 3, 7 and 8, the two pedal units 5 are lower than the handle unit 4 in the up-down direction H and are slidably disposed on the sliding rail 24, a roller 53 capable of rolling along the sliding rail is disposed between the pedal 52 and the sliding rail 24, the roller 53 has an annular rolling surface, and the pedal 52 and the rotating shaft of the roller 53 form a fixed connection relationship. Each pedal unit 5 further includes a second mounting plate 51 disposed between a roller 53 and a pedal 52, the roller 53 and the pedal 52 are disposed on the left and right sides of the second mounting plate 51, the roller 53 is disposed on the inner side of the second mounting plate 51, and the pedal 52 is disposed on the outer side of the second mounting plate, and the roller 53 on the inner side of each second mounting plate 51 may have a plurality. The rollers 53 are arranged in a single row along the up-down direction, the rollers 53 are arranged at intervals in the up-down direction H, and the rollers 53 roll on the sliding rail 24 to drive the pedal unit 5 to slide in the up-down direction H. In other embodiments, only one roller 53 may be provided, and the pedal 52 may be directly and fixedly connected to the rotating shaft of the roller 53 without being fixed by a mounting plate.

The pedal 52 includes pedal support rods 521 provided on the left and right sides of the main frame and extending toward the front side, and pedal faces 522 fixedly attached to the pedal support rods, the pedal faces 522 being fixedly attached to the pedal support rods 521 at the lower side at the center axis thereof. When the user steps on the pedal surface 522, the directions of the feet and the directions of the pedal support rods 521 are all along the front-back direction, so that the feet can have a small displacement deviation in the front-back direction, and the support of the feet is more stable during movement. In addition, the central axis of the pedal surface 522 is fixedly connected with the pedal support rod 521, so that the distance between the two pedal surfaces 522 is relatively short, and the user can more comfortably use the utility model without too much branching of the feet.

Referring to fig. 8, the number of rollers is four, and two adjacent rollers are arranged in a group in the up-down direction of the slide rail 24, and since the main frame is inclined backward from bottom to top, when the pedal 52 moves upward, the rollers 53 receive pressure in the rear direction of the slide rail 24, and when the pedal 52 moves downward, the rollers 53 receive pressure in the front direction of the slide rail 24. Since the upward and downward speeds are different when the user moves, the roller 53 receives different pressures on the front and rear sides of the rail 24, causing different wear on the roller 53, and uneven rolling surfaces of the roller, so that the user may shake when operating the present utility model. Thus, one roller of each set of rollers is contacted with the front sliding surface 242 of the sliding rail 24, and the other roller is contacted with the rear sliding surface 242 of the sliding rail 24, namely, the roller 53 and the sliding rail 24 form single-side contact sliding, specifically: the four rollers are respectively a first roller, a second roller, a third roller and a fourth roller from top to bottom, the first roller and the second roller are in a group, the third roller and the fourth roller are in a group, the first roller and the third roller can be in contact with the front sliding surface 242 or the rear sliding surface 242 of the sliding rail, the second roller and the fourth roller are correspondingly in contact with the rear sliding surface 242 or the front sliding surface 242 of the sliding rail, the first roller and the fourth roller can also be in contact with the front sliding surface 242 or the rear sliding surface 242 of the sliding rail, and the second roller and the third roller are correspondingly in contact with the rear sliding surface 242 or the front sliding surface 242 of the sliding rail. When the pedal 52 moves upward, the roller 53 contacting the slide surface 242 behind the slide rail provides a force for upward movement of the pedal 52, when the pedal 52 moves downward, the roller 53 contacting the slide surface 242 in front of the slide rail provides a force for downward movement of the pedal 52, and the upward and downward movement speeds are different, and the force of the slide rail on the roller 43 is different, so that the roller 43 contacts the single side of the slide rail, so that the roller 43 is only pressed by the slide surface 242 on one side of the slide rail 24, the wear is even, and the shake caused by uneven wear of the roller is eliminated. When only one roller 53 is in contact with both the front and rear sliding surfaces, attention should be paid to the matching precision of the roller 53 and the convex rail 241, and the processing precision of the roller 53 and the convex rail 241 is required to be high. In other embodiments, the plurality of rollers 53 may be two or six or eight, etc. in two groups, and two rollers may be less costly, but the stability may be correspondingly poorer due to the shorter length of the second mounting plate with a smaller number of rollers. The stability of the second mounting plate 51 and the pedal 52 is improved by more than four rollers, but the cost of the rollers is correspondingly increased by increasing the number of rollers 53. The number of the rollers can be two or two, and the two rollers are respectively contacted with one sliding surface 242 of the front sliding surface 242 and the rear sliding surface 242, so that the rollers are uniformly worn.

Similarly, in other variations, the rollers 53 may be double-row rollers, or the rollers 53 may be self-lubricated guide sleeves, and the sliding action may be achieved by matching the guide rail 24 with a guide post type design.

Referring to fig. 5 and 8, the rolling surface of the roller 53 is a cylindrical surface, the cross section of the rolling surface is in an h shape with a low middle and high two sides, the middle of the rolling surface is in a straight line, the shape of the convex rail 241 is a rectangle matched with the roller 53, therefore, the middle of the roller is a rolling surface matched with the sliding surface 242 of the convex rail 241, two sides of the rolling surface are constraint surfaces, the constraint surfaces are contacted with the left and right side surfaces of the convex rail 241 to limit the roller to the left and right sides of the convex rail 241, the roller 53 rolls along the sliding rail 24 in the up-down direction, the constraint surfaces can prevent the roller 53 and the pedal 52 connected with the roller from moving left and right, and accordingly, the sliding surface 242 is a plane. The I-shaped roller and the rectangular convex rail are common, so that the processing maturity is high, the processing is easy, and the cost is low. In other embodiments, referring to fig. 6, the rolling surface of the roller 53 is a progressive conical surface, the cross section of the roller is a middle low side high side ") (" type ", and correspondingly, the cross section of the convex rail is a convex arc matched with the roller. At this time, the cross section of the sliding rail is circular or arc-shaped or the combination of arc and straight line has arc shape, but it should be noted that the shapes of the sliding rail 24 and the roller 53 should limit the movement of the roller 53 in the left-right direction of the sliding rail 24, so as to avoid the left-right movement of the pedal 52. The rolling of the roller 53 on the track is smoother, but the manufacturing cost is slightly increased, because the transition between the rolling surface and the restraining surface is more rounded.

Referring to fig. 2 to 6, since the protruding rail 241 is disposed in the front-rear direction of the sliding rail 24, the sliding surface 242 of the sliding rail 24 contacting with the roller is also in the front-rear direction of the sliding rail 24, the rotation axis of the roller extends toward the left-right direction of the sliding rail 24, so that the force can be applied to the rolling surface when the user acts, and the handle and the pedal extend forward, so that the pedal is located in front of the main frame 22, and therefore the user can avoid the main frame without having to diverge the legs, thereby conforming to the action habit of the user and having high movement comfort. In addition, because the gravity center of the user is always at the front side of the frame in the use process, the force applied by the user to the roller 43 is vertical to the corresponding rolling surface, and compared with the mode that the handle extends outwards in the prior art, the roller 43 is not subjected to lateral torsion force from the user, the problem that the end surface of the roller 43 is in friction interference with the lateral inner wall surface of the slide rail 24 is solved, and the service life of the rock climbing machine is prolonged.

Referring to fig. 3, 7 and 8, the linking mechanism 6 is used for linking the handle unit 4 and the pedal unit 5, and the linking mechanism 6 of the present embodiment includes an upper pulley 601, a lower pulley 602, a pulley block 603, a handle pull cable 604, a pedal pull cable 605, a first pull cable 606 and a second pull cable 607.

With continued reference to fig. 3, 7 and 8, the upper pulley 601 is disposed at the top side of the main frame 22, the lower pulley 602 is opposite to the upper pulley 601 in the up-down direction H and is disposed at the bottom end of the main frame 22, and an adjusting and positioning unit is disposed between the upper pulley 601 and the lower pulley 602, the adjusting and positioning unit in this embodiment is a bolt fixing member 62, the lower pulley 602 is connected with the bottom end of the main frame 22 through the bolt fixing member 62, and has a rotatable adjusting nut, and the connection length between the lower pulley 602 and the bottom end of the main frame 22 can be finely adjusted by rotating the nut of the bolt fixing member 62, so that the distance between the lower pulley 602 and the upper pulley 601 is adjusted and positioned, thereby tensioning each cable member (the handle pull cable 604, the pedal pull cable 605, the first pull cable 606 and the second pull cable 607) of the linkage 6 will be loosened after long use. Of course, the adjusting and positioning unit may be disposed on the top side of the main frame 22 to adjust and position the upper pulley 601, but the operation is relatively inconvenient.

With continued reference to fig. 3, 7 and 8, the pulley block 603 is located between the two handles 42 and the two pedals 52 and has four pulleys 63, the pulleys 63 are disposed on the main frame 22 in pairs at intervals in the up-down direction H and the left-right direction W, and the two pairs of pulleys 63 are staggered back and forth. So that the front first pulling rope 606 and the rear second pulling rope 607 can be wound in a transverse Z shape to realize the crossing and the winding of the pulley block 603. The handle pulling rope 604 is slidably wound around the upper pulley 601, and both ends thereof are respectively connected to the top sides of the two first mounting plates 41, so that the two handles 42 can simultaneously reversely act one above the other, and the handle pulling rope 604 of the present embodiment is a belt, and the upper pulley 601 of the present embodiment is a belt pulley. The pedal pulling rope 605 is slidably wound around the lower pulley 602 and has both ends connected to the two second mounting plates 51, respectively, so that the two pedals 52 can be reversely actuated one above the other at the same time. The first cable 606 is connected to the bottom side of the left first mounting plate 41, and is connected to the top end of the right second mounting plate 51 after passing around one pair of pulleys 63 in a transverse zigzag shape, so that the left handle 42 and the right pedal 52 can be actuated upward or downward (in the same direction). The second cable 607 is connected to the bottom side of the first mounting plate 41 on the right side and is connected to the top end of the second mounting plate 51 on the left side after being passed around the other pair of pulleys 63 in a transverse zigzag shape, so that the handle 42 on the right side and the pedal 52 on the left side can be simultaneously actuated upward or downward (actuated in the same direction).

In order to reduce the inclination of the first and second cables 606 and 607, the pulley 63 on one side in the lateral direction may be shifted to the outside of the main frame on the side so that the first and second cables 606 and 607 approach the vertical direction H, the pulley 63 on the other side in the lateral direction may be shifted to the outside of the main frame on the side so that the first and second cables 606 and 607 approach parallel to the vertical direction H, and at this time, the pulling force of the handle extending outward on the first and second cables 606 and 607 is nearly perpendicular to the first and second cables 606 and 607, and the lateral force applied to the first and second cables 606 and 607 is small. In addition to shifting the pulleys 63 to the left and right sides as much as possible, the height of the pulleys 63 should be set so that the directions of the first and second stay 606, 607 between the two pulleys 63 approach the left and right direction W. The closer the first and second guy wires 606, 607 are arranged to be parallel to the up-down direction H, the smaller the pressure the first and second guy wires 606, 607 exert on each pulley 63 of the pulley block 603, reducing wear of the first and second guy wires 606, 607 and the pulleys 63, improving the service life of the apparatus. Meanwhile, the smaller the lateral force received by the first pull rope 606 and the second pull rope 607, the smoother the first pull rope 606 and the second pull rope 607 and the handle and the pedal connected with the same move, and the problem of unsmooth movement of the pedal and the handle can be solved.

In addition, since the first and second pull cables 606 and 607 are sequentially wound around the two pulleys 63, respectively, the diameters of the pulleys 63 can be reduced on the basis of ensuring the directions of the first and second pull cables 606 and 607, and thus the width of the main frame 22 can be reduced, the user can reduce the width of the hand and foot diverges when operating the present utility model, and the comfort of movement can be improved.

Similarly, in order to reduce the inclination of the handle stay 604 and the pedal stay 605, the widths of the upper pulley 601 and the lower pulley 602 should be controlled such that the line connecting both sides thereof with the front of the first mounting plate is substantially parallel to the up-down direction H, so that the handle stay 604 and the pedal stay 605 are substantially parallel.

Each handle 42 can rotate relative to the corresponding first mounting plate 41 by taking the axis X as the rotation center, and an adjusting piece 46 which is adjustably arranged on the handle 42 in a penetrating way and positioned on the corresponding first mounting plate 41 is arranged on the outer side of the first mounting plate 41. Each handle 42 has a rotary seat 421 rotatably coupled to the fixed disk 45, and a handle body 422 extending from the rotary seat 421, the rotary seat 421 has a through hole 423 extending along the axis X and through which the rod body 442 of the fixed member 44 passes, the end surface of the rotary seat 421 connected to the fixed disk 45 has a plurality of engagement teeth 424 surrounding the axis X and angularly offset from each other, and the engagement teeth 424 surround the through hole 423.

Since the handle fixing sections 425 extend toward the user, the distance between the two handle fixing sections 425 is relatively short, and in this embodiment, the grip section 426 of the handle extends and bends from one end of the handle fixing section 425 to the outside in the left-right direction, so that the user can separate the two arms to both sides, grip the handle 42 more conveniently, and the comfort level of the user can be improved. Each adjusting member 46 is inserted through and pressed against the corresponding rotating seat 421 and is locked on the corresponding fixing member 44, each adjusting member 46 has a locking section 461 screwed into the corresponding screw hole 443, a tightening section 462 connected to the locking section 461 and having a larger outer diameter, a step formed by reducing is used for pressing against the rotating seat 421, and a force application portion 463 connected to the tightening section 462 and used for allowing the hand of a user to rotate, specifically, the force application portion 463 is a knob.

After adjustment, the engagement teeth 424 of the rotary seat 421 are engaged with the engagement teeth 452 of the fixed disk 45, and the adjustment member 46 is then screwed back to fix. The angle of rotation of each of the engagement teeth 424 and the engagement teeth 452 is the same, and the smaller the angle of each tooth, the finer the handle can be adjusted. When in use, a user can adjust the height of the handle 42 according to the height of the user, for example, a person with a higher stature can rotate the handle 42 and adjust the gripping section 426 to increase the distance between the handle 42 and the pedal 52 on the same side; a person of a smaller size can lower the grip segment 426 of the handle 42, reducing the distance between the same side of the handle 42 and the pedal 52.
